More and more builders are discovering the advantages of quick-change rearends, which allow you to change your final drive ratio from highway-friendly to track-ready with a simple 10-minute gear change. For those building high-performance trucks with an eye toward road racing and autocrossing, Winters Performance offers a fully independent quick-change rear in addition to their standard solid-axle rears. They’re available in either the smaller V-8 independent, with an 8 3/8-inch 3.78 ring-and-pinion that’s rated for up to about 600 hp, or a larger Champ Independent with a 10-inch 4.12 ring-and-pinion rated for 1,000-plus horsepower. Both are equipped with Winters’ limited-slip differential and a range of output flanges, from Corvette style to Porsche 930 and 934 style, making installation simple. Finish options from natural cast and fully polished to an all-new, all-black Teflon coating means there’s an independent quick-change for every style of custom truck. For an even more custom appearance, you can even choose an anodized aluminum gear cover and Winters will etch your logo or design at no additional cost.
